The bestselling book that asks what dogs know and how they think. The answers will surprise and delight you as Alexandra Horowitz, a cognitive scientist, explains how dogs perceive their daily worlds, each other, and that other quirky animal, the human.

One of the most acclaimed nonfiction books of 2011, Susan Orlean’s New York Times bestseller Rin Tin Tin is “an unforgettable book about the mutual devotion between one man and one dog” (The Wall Street Journal).

A firsthand exploration of the extraordinary abilities and surprising, sometimes life-saving talents of “working dogs”—pups who can sniff out drugs, find explosives, even locate the dead—as told through the experiences of a journalist and her intrepid canine companion, which TheNew York Times calls“a fascinating, deeply reported journey into the…amazing things dogs can do with their noses.”
